php - codeigniter $this->dbutil->csv_from_result ignore last delimiter -

i using following function export csv.

$this->dbutil->csv_from_result() 

unfortunately @ end of line prints delimiter, when use csv import data again takes field out key. example here:

"id", "time", "name",

"1", "1400000000", "john",

"2", "1400000000", "matt",

wondering if can this.

you can use

rtrim($string, ","); // strip comma end of string

example :

$string = "abc" ;   echo rtrim( $string , "c") ;   echo ab
